above and within the ocelli. There is a slender impressed median line, 

 black or dark brown ; and a depressed spot upon each side appears 

 midway Iietween this and the eye. 



Front, bluish black, with a few yellow median points and a row 

 of transverse yellow lines interrupted across the middle. Cheeks 

 black above, yellow behind; basal joint of the antennse blackish be- 

 neath ; clypeus black in the middle and at the margins, yellow at 

 the sides. Lores yellow, bordered with black. Pronotum longer 

 than the head, but slightly narrower, strongly arcuate in front, base 

 nearly straight, yellow anteriorly (where it is also mottled with 

 white), shading to dark green posteriorly, owing to the black tint 

 in the mesonotum showing through the transparent pronotal 

 shield. A few faint dusky blotches just behind the eyes. 



Scutellum yellow somewhat mottled with white except two deeper 

 yellow^ blotches just within the lateral angles. A very slender black 

 impressed line. Hemelytra yellowish hyaline, veins yellowish green; 

 the costal margin broadly thickened, punctulate. 



Tergum black, posterior margins of the segments yellow. Thorax 

 bluish black beneath, except the outer margins of the lateral plates 

 of the mesothorax, which are yellow. Abdominal segments blue- 

 black, bordered with yellow posteriorly, the two or three last seg- 

 ments largely yellow-black, or dusky only in front. The hypopygium 

 nearly all yellow, connexivum chiefly yellow irregularly mottled 

 with blue-black. Valvules of the female yellow beneath and behind, 

 black above and in front, spinose with long yellow bristles. 



Coxfe all blue-black ; anterior and middle femora with about two 

 rings of black, tibiae irregularly and variably specked or ringed with 

 black, legs otherwise pale, except the points of attachment of the 

 larger spines, which are black. 



Total length .14 inch ; length of head .001 inch ; of thorax .013 

 inch ; of scutellum .013 inch ; width of head .038 inch ; width of 

 scutellum .025. 



This species was collected by Mr. Garman at Mount Carmel on 

 the '2Sth of May, 1884, where it was abundant in growing oats ; at 

 DuQuoin on the 7th June, where he found it common in young wheat 

 and again on the 5th July, when it was obtained by sweeping in 

 wheat stubble. At Anna, July 14, it was very common on young corn, 

 and occasionally occurred upon musk melons, August 2. 



Cicadula quadriUneatus, n. s.* 



(Plate V. Fig. 4.) 



Similar in general appearance to Cicadida nigrifrons, but differing 

 in wing veins and color markings. Head with two round black 

 spots upon either side of the middle of the base, about equidistant 

 from the median impressed line and from the eyes. In front of 

 these a transverse black line extending from eye to eye but inter- 



*Differs from the preceding and from typical European species of Cicadula by some 

 structural characters; but the above generic assignment expresses its true relations.
